Assuming that a planet with an atmosphere already existed which orbits at the radius of the termination shock of a star, what would happen to it over time?
As a follow-up, would it be possible for a ...

I wanted recommendations of dynamo theory pdfs to make a report about magnetic fields of planets and stars with all the math behind it, like vector calculus, Lagrange functions, partial differential ...

There's a lot of interesting stuff coming from New Horizons about Pluto, but are we actually gaining any non-trivial scientific understanding from it, or is it all just "oh neat, Pluto has mountains ...

When the comet Shoemaker-Levy 9 impacted with Jupiter it created a ball of fire 3000 Km high and it left a mark on the surface of the planet that was visible for weeks (source: Wikipedia). How was the ...

Super excited with this latest discovery! For those unaware, NASA just released news on a "bigger, older cousin to Earth", named Kepler 452-b! Here's some more information (please feel free to correct ...

I have searched for equations regarding craters and I came across two of them. The first one is from this NOAO website in the level two section. There, it says that,
$$
D^3\propto E
$$
where $E$ is ...

They say that gravity Decreases as we dig into the earth. But I also read that gravity increases for the first approx. 2000km of distance underground. Using this rational, could we dig about 200 to ...

It's a well known problem that Earth is slowly losing its supply of helium due to helium's ability to "bubble off" the atmosphere. All the gas giants have significant percentages of helium in their ...

How would you calculate the mass of a sun that could host a habitable planet, with only given the values of the mass of our own sun. And the fact that it takes a specific amount of years for life to ...

I have been reading about Jupiter as of late and reason I am asking is if Jupiter has strong enough gravity to pull hydrogen to itself then it should be only matter of time when it will acquire enough ...

Lets say the Earth is hollow and you are in the center of it (Same mass except all of it is on the outside like a beach ball) If you move slightly to one side now your distance is closer to that side ...

In the early stages of the solarsystem rocks clumped together randomly until their gravity drew in more material which led to protoplanet formation. But how does the dust and do the rocks form bigger ...

I wish to figure out how the flux of the sun's reflected light from a planet varies with distance, so assume an observer is on the sun, looking at a planet, and the light originating from the planet ...

Imagine, if you will, there exists somewhere out there a supermassive planet. For some reason, this planet is only a shell of its former existence and all that is left is a crust of substantial size ...

The book Mission of Gravity describes a planet with a mass of 16 times Jupiter spinning at a rate of one revolution every 17.75 minutes. This causes it to stretch out into an oblate spheroid and has ...

1) Are we able to study any other solar systems, that once contained a sun the size of our own... that has since died, or gone Red Giant, the way it is predicted our sun will die?
2) If we have been ...

In the news recently was the announcement that the answer to the classic Newtonian mechanics question of the time it takes for a body to fall all the way through the Earth was corrected to account for ...

Provided that the Solar System consists only of Sol, a planet, and the planet's moon....
How large can my planet be so that it has low enough gravity that teenage human girls trained for jumping, are ...

is it possible to prove that planets (and/or stars) are always round (elliptical if you consider the spin)? Is there a set of equation that demonstrate that fluids (after all, molten rocks "floating" ...
